Tony,
The only way to do this without adding static routes is to add a default-networ
k command at router A. The things to remember in doing this is that the defaul
t network must point to a route that router A knows about and you must keep it
classfull. For instande, say that router A also knows about network 10.1.1.0/2
4. Then, to send a default to router B you need to configure "ip default-netwo
rk 10.0.0.0" glabally in router A. If you made the mistake of putting "ip defa
ult-network 10.1.1.0" in the router, you will see that a static route will be i
nserted into the config automatically, and you said that static routes are not
allowed.
Oh yes, one last thing. Make sure that router B has "ip classless" configured
also in order to make this work. Everyone else, if I am wrong in any way or if
I forget something, please add to this.
I will also be in RTP on Nov. 20 taking my lab test. See you then!

All,
I am working on a practice lab on one of the midwest channels racks and am havi
ng a problem with redistribution. Here's a sample config:
Router A
!
router ospf 100
network 172.17.59.32 0.0.0.15 area 0
network 172.17.59.48 0.0.0.15 area 2
network 172.17.59.64 0.0.0.63 area 3
redistribute igrp 100 metric 64 subnets
!
router igrp 100
network 172.17.0.0
redistribute ospf 100 metric 64 10 255 1 1500
Router B
!
router igrp 100
network 172.17.0.0
!
Here's the deal, IGRP does not understand VLSM which is what is being used on r
outer A with OSPF. From all the docs I've read, you would have to put in static
routes on Router B to tell it how to get to those other subnets, except I'm no
t allowed to use static routes. The subnets in OSPF on Router A are not redistr
ibuting into IGRP. They come out as 172.17.0.0 instead of whatever the real net
work number is.
Here's the other thing I tried; I added these lines:
Router A
!
router ospf 100
default-information originate always
!
router igrp 100
default-information allowed in 1
default-information allowed out 1
!
access-list 1 permit any
Router B
!
router igrp 100
default-information allowed in 1
!
access-list 1 permit any
The thinking here was to originate a default route (0.0.0.0) from Router A in O
SPF and try to redistribute this into IGRP..... it didn't work. Maybe I just co
nfigured it wrong or maybe it's just not possible. I don't know. This is the se
cond time I've attempted to get this working to no avail. Let me know if you ha
ve any ideas.
Thanks,
Tony Olzak
BTW-I've just joined the list. I'm scheduled to take the test on Nov 19-20 in R
TP.
